A threat actor has shared the 2014 voter information for close to 2 million Indonesians on a well-known hacker forum. The voter records are stored in individual PDF files that they took from the KPU, the general election commission of Indonesia. Cyber intelligence firm Under the Breach, who shared a sample with BleepingComputer, stated that these PDFs were organized by Indonesia cities. The KPU tweeted a statement that the data was not leaked or hacked, but that it was public information to anyone during the 2014 election.
